What is LAANC and how does it work for drone pilots?

LAANC, which stands for Low Altitude Authorization and Notification Capability, is an FAA system that provides drone operators with near-real-time airspace authorization to fly in controlled airspace at or below 400 feet AGL. Pilots submit authorization requests through FAA-approved UAS service suppliers (USS), and approvals are typically granted in seconds based on established UAS Facility Maps (UASFMs) that define ceiling altitudes where automatic approval is available. LAANC replaces the older, manual Part 107 waiver process for most routine operations in controlled airspace, dramatically reducing wait times from days or weeks to near-instant responses.

Does LAANC authorization replace the need for a Part 107 Remote Pilot Certificate?

No, LAANC authorization and a Remote Pilot Certificate are separate requirements that serve different purposes. Under 14 CFR Part 107, a remote pilot certificate is required to legally operate a small UAS for non-recreational purposes, while LAANC provides the airspace authorization needed to fly in controlled airspace. Both requirements must be satisfied independently — holding a LAANC authorization does not waive the certificate requirement, and holding a Remote Pilot Certificate does not automatically authorize operations in controlled airspace.

What's the difference between LAANC authorization and a Part 107 airspace waiver?

LAANC provides automated, near-real-time authorization to operate in controlled airspace at or below the ceiling altitudes published on UAS Facility Maps, making it ideal for routine operations that fall within those predefined parameters. A Part 107 airspace waiver, submitted through the FAA DroneZone portal, is required when a pilot needs to exceed those UASFM ceiling altitudes or operate under conditions that cannot be approved automatically by LAANC. Waivers involve a more detailed safety case review by the FAA and can take significantly longer to process, so LAANC is the preferred option whenever the operation fits within the approved parameters.

LAANC System for UAS Airspace Authorization

One of the most practical tools a Part 107 remote pilot will use in day-to-day operations is the Low Altitude Authorization and Notification Capability, universally known as LAANC (pronounced "lance"). Before LAANC existed, a remote pilot who needed to fly in controlled airspace had to submit a manual airspace authorization request to the FAA and wait — sometimes weeks — for a response. LAANC changed that paradigm entirely by automating the authorization process through a network of FAA-approved UAS Service Suppliers (USS), giving most pilots a "yes or no" answer in seconds rather than days. Understanding how LAANC works, where it applies, and what its limitations are is essential both for the FAA Part 107 knowledge test and for safe, legal drone operations.

LAANC is a public-private partnership between the FAA and approved technology companies that serve as the interface between remote pilots and the FAA's airspace data. Rather than calling a control tower or filing paperwork, a pilot opens an approved LAANC app, selects an operating area, specifies an altitude, and receives an automated authorization to fly — all in near-real time. This system is now active at hundreds of controlled airports across the United States, covering Class B, C, D, and surface Class E airspace where drone flights would otherwise require prior ATC authorization under 14 CFR Part 107.41.

How LAANC Works

The backbone of LAANC is a set of geographically defined grids called UAS Facility Maps (UASFMs). The FAA publishes these maps for each participating airport, and they display the maximum altitude, in feet AGL, at which the FAA has pre-evaluated that drone operations can be automatically authorized in each grid square. A grid square directly under a busy approach path might show "0 feet," meaning no automatic authorization is available there, while a grid square several miles from the runway might show "200 feet" or "400 feet."

When a remote pilot submits a LAANC request through an approved USS app, the system checks the proposed operation — location, altitude, and time — against the UASFM data. If the requested altitude is at or below the ceiling shown on the UASFM for that grid, the authorization is granted automatically and nearly instantly. This is called an automatic authorization. If the pilot needs to fly higher than the UASFM ceiling, or in a grid showing "0 feet," the request cannot be automatically approved; the pilot must instead apply for a manual FAA DroneZone authorization, which follows a traditional review process. FAA guidance recommends submitting these manual requests at least 90 days in advance, though actual processing times can vary.

It is important to understand that LAANC authorization is site-specific and time-specific. The authorization covers a defined geographic area and a defined time window. If your operation changes — you move to a different grid, fly higher, or extend your operating time beyond what was approved — you are no longer operating under that authorization and must seek a new one.

Where LAANC Applies

LAANC is available only in controlled airspace at participating airports. Remember that under Part 107, a remote pilot may fly in uncontrolled airspace (Class G and most Class E airspace that does not extend to the surface) without any prior airspace authorization, as long as all other Part 107 rules are followed. The authorization requirement — and therefore the need for LAANC — arises specifically when operating in:

Class B airspace — the large, layered airspace surrounding the busiest commercial airports
Class C airspace — the two-ring airspace around airports with moderate traffic and a staffed radar approach control
Class D airspace — the smaller cylindrical airspace around airports with an operating control tower
Class E surface airspace — Class E airspace that extends to the surface, usually designated around airports with instrument approaches but no control tower

Not every airport that has controlled airspace participates in LAANC. At non-participating facilities, remote pilots must use the manual FAA DroneZone process. The list of LAANC-participating airports is maintained by the FAA and is searchable through approved USS apps.

UAS Facility Maps and Altitude Ceilings

The UAS Facility Map is the document that makes LAANC function. The FAA analyzes the traffic flow, instrument approach corridors, and overall airspace complexity around each participating airport, then assigns a maximum altitude to each grid square, up to 400 feet AGL. Key points about UASFMs include:

A grid showing "0 feet" means automatic authorization is not available; any operation there requires a manual waiver.
A grid showing "400 feet" does not mean a pilot can automatically fly at 400 feet everywhere in that grid — the standard Part 107 400-foot ceiling still applies, and additional constraints (like proximity to structures) may govern the actual operating altitude.
UASFMs are updated periodically and reflect the FAA's ongoing evaluation of safe drone integration at that airport. Always check the current map before each operation.
UASFM data is embedded in every FAA-approved LAANC USS app, so pilots do not need to locate and read a separate chart manually — the app displays the relevant ceiling for the selected area.

Approved UAS Service Suppliers

LAANC does not operate through an FAA website alone; it is delivered through FAA-approved UAS Service Suppliers. The FAA certifies these third-party companies to access the national airspace data and process authorization requests. Popular examples include apps from aviation data companies and drone manufacturers. The FAA maintains a current list of approved USS providers. A remote pilot should always verify that the app they are using is on the FAA's approved list — an unofficial or non-approved app cannot grant a valid LAANC authorization, and flying on a fake or invalid authorization is the same as flying without any authorization.

Why LAANC Matters for Safety and Compliance

LAANC exists because drones and manned aircraft must share the same airspace safely. Controlled airspace exists precisely because aircraft operating there are separated and managed by ATC. When a drone enters that airspace without authorization, it creates a potential mid-air conflict that neither the drone pilot nor the manned aircraft crew may be able to avoid. LAANC addresses this by ensuring that the FAA — and by extension, the relevant ATCT — has been notified of the drone's presence before flight begins.

From a compliance standpoint, operating in controlled airspace without an authorization under 14 CFR 107.41 is a violation that can result in significant civil penalties (subject to periodic inflation adjustments under 14 CFR Part 13) and potential certificate suspension or revocation. LAANC is the fastest and most accessible path to compliance, and using it correctly demonstrates the kind of airmanship and safety culture the FAA expects of certificated remote pilots.

Key Numbers and Rules

14 CFR 107.41 — the rule requiring ATC authorization before operating in controlled airspace
400 feet AGL — the standard Part 107 altitude ceiling; LAANC cannot authorize flight above this limit through the automatic process
0 feet on UASFM — no automatic authorization available; manual DroneZone request required
Near-real-time approval — typically seconds to minutes for automatic authorizations at or below UASFM ceiling
Manual authorization timeline — FAA guidance recommends submitting manual DroneZone requests at least 90 days in advance
Class B, C, D, and surface Class E — the four categories of controlled airspace where LAANC authorization applies
Class G and non-surface Class E — generally no prior authorization required; LAANC not needed

Common Test Traps

LAANC is not a waiver. A common misconception is that LAANC provides a waiver from Part 107 rules. It does not. LAANC is an airspace authorization — it allows you into controlled airspace. It does not waive any other Part 107 requirement such as the daylight rule, visual line-of-sight, or the 400-foot ceiling.
LAANC cannot authorize above 400 feet AGL. Even if a UASFM shows 400 feet, LAANC's automatic authorization process is bounded by the standard Part 107 ceiling. Flying above 400 feet requires a separate Part 107.51 waiver, not a LAANC authorization.
A "0 feet" UASFM grid does not mean you can never fly there. It means automatic authorization is unavailable. A manual FAA DroneZone authorization can still be requested and may be granted after FAA review.
LAANC authorization is time-limited and location-specific. Test questions may describe a scenario where a pilot has LAANC approval for one grid but flies into an adjacent grid — that operation is unauthorized, even if both grids are near the same airport.
Only FAA-approved USS apps provide valid LAANC authorizations. Using a non-approved flight planning app, even one that displays airspace data, does not constitute a valid LAANC authorization.
